UNITIEDVQS'FIATES PATENT OFFICE FRANK o. enonosxr, or sou'rn CHICAGO, ILLINOIS GAS SAVING DEVICE Application filed June 19, 1928. Serial No. 286,680.

I This invention relates to improvements in a flat sided plate 71 which is preferably of carburetor attachments and more particuthe same marginal contour as the flanges larly to an attachment for installation of 69 and 70 and this plate is formed centrally tween the carburetor and intake manifold of with an opening 7 2 which substantially regthe internal combustion engine of an autoisters with the bores of the carburetor out" :35 mobile, and one of the objects of the invenlet-branch 67 and the intake branch 68 of tion is to provide an attachment by the use of the intake manifold, the plate 71 being arwhich a great saving in gasoline may be ranged between the said flanges 69 and 70 effected thus materially reducing the cost of and held in place by the usual bolts 7 3 which operation of the engine. a are provided for securing these flanges tot0 Another object of the invention is to progether. A packing gasket 7 1 is interposed vide a carburetor and intake manifold atbetween the flange 69 and the plate 71, and tachment so constructed that a more thora similar gasket 75 is interposed between ough mixture of the gasolineandair will be the flange 70 and the said plate 71 and this 15 effected thereby greatly increasing the efiiclatter gasket 7 5 is formed with an opening 76 be iency of the engine. which is concentric to the opening 72 in the Another object of the invention is to proplate 71, and a circular sheet 77 of fine wire vide an attachment of the class described so mesh material is arranged within the openconstructed that the vaporized gasoline will ing 76 in the gasket 75 and rests at its pebe thoroughly broken up and intimately ripheral portion upon the upper side of the it mixed with sufiicient air to insure of more plate 71 and extends overthe opening 72 in thorough combustion of the explosive mixsaid plate, this screen serving the same purture, in the engine cylinders, than is pospose as the screen 21 of the first described sible by the use of the ordinary carburetor. embodiment of the invention. as \Vhile the accompanying drawings and The butterfly valve of the carburetor is inthe description which is to follow, constitute dicated by the numeral 78 and is supported a disclosure of the preferred embodiment of upon the usual rod 79 mounted in the outlet the invention, it will be understood that varibranch 67 of the carburetor, this valve correous changes may be made within the scope of sponding to the valve 4 in the first described so What is claimed. embodiment of the invention. Air passages In the accompany'ng drawings: 80 are formed in the plate 71 and as shown in Figure 1 is a vertical diametric sectional Figure 2, extend between the wall of the openview illustrating a further modification of ing 72 and opposite edges of the plate, these the invention. passages providing for the flow of air into the Figure 2 is a horizontal sectional view fuel conduit comprising the carburetor outtaken substantially on the line 1212 of Figlet branch 67 and intake manifold branch 68 ure 1 looking in the direction indicated by in regulated quantities, as will now be madev the arrows. apparent. The numeral 81 indicates a rod Figure 3 is a horizontal sectional view which is mounted for rocking movement at taken substantially on the line 13-13 of Figits ends in bearing openings formed in the t6 ure 1 looking in the direction indicated by plate 71 at opposite sides of the opening 72, and arcuate valve plates 82 are fixed at their By referring to the drawings it will be seen inner ends as at 83 upon the shaft 81 and close that the outlet branch of the carburetor bowl to the wall of the opening 72, and these valve is indicated by the numeral 67 and the inplates extend circumferentlally of the wall take branch of the intake manifold is indiof the opening and the outer end of each plate cated by the numeral 68, these parts being normally extends over and closes a respective provided respectively with the usual flanges one of the passages 80. An arcuate finger 8d indicated by the numerals 69 and 7 O. The is united to the shaft 81 at the center of the attachment, in this embodiment comprises opening 72 in the plate 71 and is provided 0 as I at its free end with a spherical weight 85. By reference to Figure 1 it Will be observed that when the valve 78 is in closed position, the weighted end of the finger 84 will rest upon the valve at one side of the stem 79, and in this position of the valve and the rod 81, the Valve members 82 will occupy the position shown in Figures 1 and 2, in which position they will close the inner ends of the respective passages 80. However when the valve 78 is opened and the engine is set in motion, the tilting movement of the valve 78 to open or partly open position will relieve the weighted end of the finger 84 of support and therefore this finger will swing downwardly, by gravity thus rocking the rod 81 and swinging the valve members 82 downwardly clear of the inner ends of the passages SOth-us permitting the intake of air into the fuel conduit to mix with the fuel before its passage to the intake manifold of the engine.

It will be evident that the inventive idea involved is that of arranging a screen in an explosive fluid conducting conduit, together with a battle, and the provision of means for admittin air into the conduit it bein understood that the screen and baffle and the air inlet ports and controlling valves therefor, need not necessarily be located at the juncture of the intake branch of the inlet manifold and the delivery branchof the carburetor, but that this is merely a convenient place to locate the apparatus of the invention. Having thus described the invention, what claim is:

1. A gas saving device of the class described, an explosive mixture conduit, means for admitting a gas thereto, a valve within the conduit for controlling the flow of gas through the conduit and supported for tilting movement within the conduit, about :an axis diametric to the conduit, a screenin the conduit above the valve, .the conduit having an air inlet passageway communicating therewith and with the atmosphere, a rod mounted for rotative movement diametrically of the conduit above the said valve, a valve plate upon the rod extending along the wall of the conduit and adapted to cover and uncover the inner end of the passageway. in the rocking movement of the rod, and a finger extending downwardly from the rod .and having a weighted lower end resting upon the valve at one side of the axis thereof, the valve constituting a means for supporting the finger in an elevated position to maintain the valve plate upon the rod in a position closing the inner end of the passage in the closed position of the valve and the weighted finger constituting means for rocking the said rod to having an air inlet opening formed in the side thereof, a valve member pivotally mounted upon the interior of the body and adapted to be swung over said air inlet opening for closing said opening, a gas control valve mounted within the conduit below said body, and means carried by said valve member and engagingsaid gas control valve for swinging said valve member for opening and closing said air inlet as said gas control valve is operated.

3. A gas saving device of the class described,a conduit an annular body interposed in the length of the conduit, said body having air inlet openings extending transversely theret-hrough, a-shaft extending transversely through the center of said body and constituting a journal, valve members fixedly secured to said shaft and conforming to the contour of the interior of said body and adapted to be swung over said air inlet openings for closing said openings at desired peiods, a control finger projecting laterally from said shaft and a gas control butterfly valve mounted with said conduit below the body and engaging said finger for moving said finger and consequently said valve members as said gas control valve is operated.

In testimony whereof I afiix my signature.
